Freemarker list (length, traversal, superscript, nesting, sort)

Freemarker list (length, traversal, subscript, nesting, sort) 1. Freemarker gets the size of list:

Java arraylist<string> list = new arraylist<string> ();

Freemaker ${list?size}

2.list traversal: < #list animals as being>

<tr>

<td>${being.name}${being.price}<td>

</tr>

</#list >

3.list

Subscript ordinal in traversal: _index is a property of List < #list list as a>

${a_index}

</#list >

4. Nesting of list:

< #list jssklist as jsskvo>

< #list kclist as kcvo>

< #if kcvo.kch=jsskvo.kch>

（

There are numbers and names in the KCVO, and jsskvo only numbers) ${KCVO.KCM}

</#if >

</#list >

</#list >

5. List sort: Ascending. sort_by ()

< #list list?sort_by ("field") as X>

</#list >

Descending. Sort_by ()? Reverse < #list list?sort_by ("field")? Reverse as X>

</#list >
